Seventh Circle Audio

So, I finished my rack, everything passed the initial tests fine and so far all modules are sounding great. Oddly when turning the gain on my J99 fully clockwise all sound disappears at "12". Totally normal up to there. Obviously I'll be pulling it out and checking all the solder on the Grayhill, but I thought I'd just ask and see if anyone knew exactly what would cause such a phenomenon and since I didn't see this on the forum help out anyone else who does whatever I did wrong in the future.

Yep, well, turns out it's helpful to have the adhesive foil holding in the stop pin oriented the way it's supposed to go...as opposed to perpendicular at 90 degrees. Chassis filled, sounds great, worry free time to play
